Boca filed their appeal to sport's highest court on Friday after the South American Football Confederation (CONMEBOL) rejected their claim that River Plate should be disqualified from the continent's equivalent of Europe's Champions League.

CONMEBOL, the governing body for South American football, turned down a previous request last week.

"The Court of Arbitration for Sport (CAS) has dismissed an urgent request for provisional measures filed yesterday by CA Boca Juniors in which it sought to suspend the second leg of the final of the Copa Libertadores," CAS said in a statement.

The organisation said it would nevertheless hear the merits of Boca's appeal at an undisclosed later date.

The teams drew the first leg 2-2 at Boca's Bombonera ground on Nov. 11.
